Open-Label Randomized study to evaluate linvoseltamab versus EPd in R/R Multiple Myeloma

What is the Purpose of this Study?

We are doing this study to find the most effective, safe dose of an experimental drug called linvoseltamab (the study drug) compared to a combination of three cancer drugs(elotuzumab, pomalidomide, and dexamethasone) for people who have multiple myeloma.

What is the Condition Being Studied?

Relapsed and Refractory Multiple Myeloma

Who Can Participate in the Study?

Adults ages 18+ who:

  • Are diagnosed with multiple myeloma
  • Have received at least one previous round of treatment that included lenalidomide and a proteasome inhibitor without having a satisfactory response
  • Have not received more than 4 rounds of previous treatment
  • Have never taken elotuzumab or pomalidomide
  • Have not received an allogeneic (donor) stem cell transplant in the past 6 months or an autologous (your own cells) stem cell transplant in the past 12 weeks

What is Involved?

If you choose to join this study, you will go through a screening period to find out if you are eligible. During this screening period, you will:

  • Have a physical exam
  • Have blood draws
  • Have a tumor biopsy

If you are eligible to join the study, you will get a random assignment (like a coin flip) to either take the study drug or take the elotuzumab, pomalidomide, and dexamethasone combination therapy.

If you are assigned to take the study drug, you will receive infusions weekly for 3 cycles (4 weeks in each cycle), followed by infusions every 2 weeks (twice per cycle) starting at cycle 4. If you have a very good response to the study drug through cycle 6 (24 weeks), you will then get the study drug once per cycle (every 4 weeks). If you are getting a positive benefit but do not show a very good response according to the study doctor, you will continue to get the study drug every 2 weeks after cycle 6 until you show a very good response.

If you are assigned to get the combination therapy, you will get elotuzumab weekly for the first 2 cycles (4 weeks in each cycle) and then once per cycle starting with cycle 3. You will take pomalidomide for the first 21 days of each cycle, and you will get dexamethasone once per week for each cycle. This study regimen will last for as long as the study doctor thinks you are benefitting.

At various visits you will complete physical exams, neurological exams, questionnaires, vital signs, scans, heart imaging, biopsy and bone marrow aspirates, urine samples, and have blood tests.
